%X Two closely related species belonging to the cultrata group show an XY condition in the male as a result of an X-autosome fusion. One of these has two cytological races which differ in the shape of the Y chromosome. This complex of XY forms has given rise to an XlX2Y species by a further Y-autosome fusion. The latter species has two cytological races which differ in the shape of the Y and X2 chromosomes, presumably as a result of the fixation of pericentric inversions and other structural changes.
